If 5 cm and 3 cm are added to the length and width of a square, the perimeter of the resulting rectangle between twice and three times the perimeter of the original square. Find the possible lengths of the sides of the original square. Write and solve a compound inequality.

where is the graph? need more info

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
